District Agreement 790 of 2020 establishes the declaration of a climate emergency in Bogotá and commits all public and private entities to work towards the sustainable development of the city. This includes the use of clean energy in all activities related to the operation and growth of the city, with the aim of fully complying with this proposal by the year 2050, according to the Bogotá 2020-2050 Climate Action Plan (PAC). One of the important aspects of the city is mobility, and the company in charge of mass public transportation is TRANSMILENIO S.A., a public entity that receives a budget from the District to improve its processes. This budget is related to the promotion of Sustainable Mobility, with the purpose of improving air quality in Bogotá and its surroundings, benefiting the inhabitants and the ecological environment. Given this context, the Bogotá Comptroller's Office plays an essential role in the control and surveillance of the management carried out by TRANSMILENIO S.A. This implies evaluating all the actions that the company implemented during 2021, specifically in relation to the use and implementation of clean energy in the city's transportation processes.
